UNITED STATES PATENT GFFIOE..

GEORGE s. eAINEs, or CORONA, ALABAMA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 490,958, dated January31, 1893.

Application tiled September 15, 1892. Serial No. 446,032. (No model.)

To all whom t may oon/cern.-

Be it known that I, GEORGE S. GAINES, residing at Corona, in the countyof Walker and State of Alabama, have invented certain new and usefulImprovements in Car-Couplings, of which the followingis a specification.

My invention relates to automatic couplers and refers more particularlyto improvements on the coupling devices shown in my patent No. 425,167dated April 8, 1890; and it consists in the novel features ofconstruction and peculiarcombination of parts hereinafterfully describedand pointed out in the claims, reference being had to the accompanyingdrawings in which Figure l is a perspective lview of my improved carcoupler. Fig. 2 is a horizontal section of tWo drawheads with myimprovements applied, coupled together. Fig. 3 is a detail view of oneof the fender sections detached and Fig. 4 is a similar view of thecoupling link.

In my other patent referred to, swinging fenders are provided which areadapted to guide the arrow head coupling link between the pin and aspring bearing plate which serves to hold such link to its coupledposition. In such construction the fender plates, have a hingedconnection with the front end of the drawhead, whereby they can be swungn out of position, to the Outside of the drawbroken, by regular use, andwhen thrown out,

to one side of the drawhead, is capable of being broken off. To overcomethese obj ections and to provide a fender plate rigidly held in thedrawhead, and which will eifectively serve for the purpose intended isthe object of the present invention.

Referring to the drawings, the drawhead A is of the usual construction,except that its link mortise B is extended rearward beyond the couplingpin apertures o a to admit of a free movement of the coupling link C,the particular construction of which will be presently described.

To one wall of the drawhead is secured a yielding bearing plate D, ofspring steel, the outer end of which is bent laterally, seated in arecess, and secured to the front edge of the said draw'nead as at d, itsinner end having a free bearing end d', which plays on the wall A of thehead as shown.

E indicates the fender, which in the pres ent case consists of a platebent to the form shown, which is rigidly secured at its ends e e in themortise B Opposite the bearing plate D.

It willobe noticed by reference to Figs. 2 and 3 that the apex or outerbent portion E' of such fender is at a point just in advance of thecoupling pin F and the front end of such fender has its lower portionout out as at E2, such cut out portion extending to a point to the rearof such pin, forming a recess at thefront end of the fender at its loweredge.

The coupling link C has its rear or pivot end reduced as at c, in whichend is the pin aperture o through which the coupling pin passes, whileits front end has an arrow coupler head c2 which head is of a thicknessin height greater than the recess formed in the fender, while its rearor pivot end is of a thickness in height somewhat less than such recess.By this construction it will be seen that the rear end of the link willhave free lateral play, in that the recess in the fender extends to rearof the pivot of such link, and as its coupling head is thicker than suchrecess it will be guided by the fender toward the pin. It will also beseen that by arranging the apex or bent edge ofthe fender slightly inadvance of the pin the link head will be guided to pass such pin andengage the yielding or spring plate D.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

l. In a car coupling, in combination, the draw, head, the coupling pin,a yielding plate at one side of the pin, a fixed fender or guide on theopposite side, having its lower front edge cut out to form a recess, andthe link having a reduced rear end adapted for'movement in said recess,and an enlarged head portion adapted to engage the fender at a pointabove such recess all as and for the purposes described.

2. In combination with the drawhead A, having the usual mortise B, andthe pin C, of

ICO

the yielding bearing plate D at one side of the pin, the outwardly bentfender or guide plate on the opposite side, having its outermost portionat apoint in advance of the pin, a cut out portion on its lower frontedge extended to a point to the rear of the pin, the link having itsrear pivotal end reduced, and movable in said recess, and a couplinghook at its front edge adapted to engage said fender at a point aboveits recess, substantially as ro described.

GEORGE S. GAINES.
